HI-8599

HI-8599 June 2006 ARINC 429 LINE DRIVER AND DUAL RECEIVER FEATURES ! ARINC specification 429 compliant ! Direct receiver and transmitter interface to ARINC bus in a single device ! 16-Bit parallel data bus ! Timing control 10 times the data rate ! Selectable data clocks ! Receiver error rejection per ARINC specification 429 ! Automatic transmitter data timing ! Self test mode ! Parity functions ! Low power ! Industrial & full military temperature ranges GENERAL DESCRIPTION The HI-8599 from Holt Integrated Circuits is a silicon gate CMOS device for interfacing a 16-bit parallel data bus directly to the ARINC 429 serial bus. This device provides two receivers, an independent transmitter and line driver capability in a single package. The receiver input circuitry and logic are designed to meet the ARINC 429 specifications for loading, level detection, timing, and protocol. The transmitter section provides the ARINC 429 communication protocol and the line driver circuits provide the ARINC 429 output levels. The 16-bit parallel data bus exchanges the 32-bit ARINC data word in two steps when either loading the transmitter or interrogating the receivers. The data bus interfaces with CMOS and TTL. The HI-8599 provides the option to bypass most of the internal output resistance so that external series resistance may be added for lighting protection and still www.DataSheet4U.com match the 75 ohm characteristic impedance of the ARINC bus. Each independent receiver monitors the data st...
